[0025] The vibration reduction assembly 200 is arranged on the upper surface of the fixed plate 105. The vibration reduction assembly 200 includes a fixed column 201, a damping plate 202, a spring 203, a hollow column 204 and a bottom plate 205. The damping plate 202 is arranged on the outside close to the fixed column 201, the spring 203 is arranged at the bottom of the damping plate 202, the hollow column 204 is arranged at the bottom end of the fixed column 201, and the bottom plate 205 is arranged at the bottom of the hollow column 204.

[0026] Furthermore, in the present embodiment, connecting holes 103 are provided at both ends of the connecting plate 101, a gap is provided between the two connecting plates 101, a connecting head adapted to the gap is provided at the bottom of the fixing plate 105, the screw-in piece 102 passes through the connecting plate 101 and the connecting head through the connecting hole 103, and is threadedly engaged with the connecting plate 101 and the connecting head, and an embedded nut is provided in the connecting hole 103 of one of the connecting plates 101, thereby realizing the rotation and tightening function of the screw-in piece 102, so that the connecting plate 101 can be adjusted for use angle under the fixing plate 105, and tightened by the screw-in piece 102.

[0027] In this embodiment, the cross-section of the connecting block 104 is T-shaped, and the front end of the connecting block 104 is set between the two connecting plates 101. The tightening piece 102 passes through the connecting plates 101 and the connecting block 104, and an embedded nut is embedded in the interior of the connecting block 104 and is threadedly matched with the tightening piece 102. The tightening piece 102 cooperates with the embedded nut to enable the connecting block 104 to adjust the use angle at the lower end of the connecting plate 101, so that the connection assembly 100 as a whole can adjust the use angle.

[0028] In this embodiment, the damping plate 202 is designed as a circular ring and is fixed to the outer side of the upper end near the fixed column 201. The two ends of the spring 203 are respectively fixedly connected to the damping plate 202 and the bottom plate 205, and surround the outer side of the fixed column 201. The damping plate 202 acts on the spring 203 to prevent the spring 203 from being in a state of continuous jumping.

[0029] In this embodiment, the hollow column 204 is designed as a bellows, and the hollow column 204 is made of a material such as rubber or polyurethane. The two ends of the hollow column 204 are respectively fixedly connected to the bottom of the fixed column 201 and the bottom plate 205. The design of the hollow column 204 enables it to buffer vibration.

[0030] In this embodiment, a piston rod 206 is fixed to the upper surface of the base plate 205, and the piston rod 206 is located inside the hollow column 204. A movable groove 207 adapted to the piston rod 206 is provided inside the fixed column 201. The piston rod 206 cooperates with the fixed column 201 with the movable groove 207 to perform piston movement, thereby achieving buffering of vibration force.

[0031] In this embodiment, a guide block 208 is fixed to the bottom end of the fixed column 201, and the piston rod 206 passes through the guide block 208 and is movably connected to the guide block 208. The movement of the piston rod 206 is guided by the guide block 208 to prevent the piston rod 206 from shifting when the hollow column 204 is performing vibration reduction.

[0032] Specifically, the connection block 104 is screwed to the rear side of the AR projection device 300, the connection block 104 is inserted into the gap between the two connection plates 101, and fixed by the screwing member 102.

[0033] In order to solve the problem that the flying vibration of the drone 400 affects the image of the AR device, a vibration reduction component 200 is set between the connecting component 100 and the drone 400, and the fixing column 201 is screwed to the bottom of the drone 400, and the bottom plate 205 is screwed to the upper surface of the fixing plate 105. When the drone 400 generates vibration force during flight, the fixing column 201 moves downward to form a piston motion with the piston rod 206, and the spring 203 on the outside of the fixing column 201 moves synchronously to reduce vibration. When the piston motion is performed, the hollow column 204 at the bottom of the fixing column 201 can also reduce vibration based on the material design, thereby reducing the vibration force brought to the AR projection device 300 by the flying drone 400, so that the projection effect of the AR projection device 300 is better;

[0034] When the projection angle needs to be adjusted, manually loosen the fastening piece 102, rotate the connecting head or the connecting plate 101 along the connecting plate 101 or the fixing plate 105 to adjust the angle as needed, and then tighten the fastening piece 102 to fix it, so as to adjust the projection angle and facilitate projection.
